LIUGONG CLG950 Final Drive Sprocket Wheel Assembly (46A0124): cqctrack’s Specialized Undercarriage Component for 50-Ton Class Lightweight Chassis

On a 50-ton class crawler excavator like the LIUGONG CLG950, the final drive sprocket is the critical link between hydraulic travel power and track motion. It meshes directly with the track chain under severe tension, transferring torque from the final drive motor into drawbar pull while enduring constant abrasive wear, shock loading, and bending stress. The OEM part number 46A0124 identifies this complete final drive sprocket wheel assembly — a high-precision, heavy-duty component engineered for continuous production in mining, quarrying, and large-scale earthmoving.

cqctrack manufactures this sprocket assembly as a specialized manufacturer of components for LiuGong 50-ton class lightweight chassis. We supply directly from our factory, ensuring that each sprocket meets the structural, metallurgical, and dimensional demands of the CLG950’s undercarriage. I’m Jack, from the cqctrack international affairs team, and I’ve personally written this article to give you a full technical understanding of the engineering and quality systems behind our 46A0124 final drive sprocket.

1. cqctrack: A Full-Spectrum OEM/ODM Undercarriage Manufacturer Serving 5t to 400t Equipment

cqctrack is a dedicated OEM and ODM manufacturer of heavy-duty tracked undercarriage systems and components. Our engineering and production capabilities span tracked machinery from 5 tonnes to 300 tonnes, and we have extended our undercarriage platform to 400-tonne-class ultra-heavy equipment. This high-capacity engineering directly supports the 50-tonne LIUGONG CLG950, where every sprocket tooth must carry extreme load cycles and resist the continuous sliding wear of track bushings.

Our products cover the complete range of tracked equipment:

• Crawler excavators (including LiuGong and all major brands)
• Bulldozers
• Crawler drilling rigs
• Crawler cranes
• Tracked loaders
• Tracked asphalt pavers
• Tracked conveyor systems

For the CLG950 specifically, we understand the design intent behind its lightweight chassis philosophy: a structure that reduces total machine weight without sacrificing structural durability. This requires undercarriage components that are dimensionally precise, metallurgically optimized, and manufactured with a controlled weight-to-strength ratio. Our broad application experience ensures that the 46A0124 sprocket fits seamlessly into this design, delivering long service life without adding unnecessary mass.

2. Self-Built Factory and 100% In-House Production for Stable, Reliable Quality

A final drive sprocket on a 50-ton excavator is a safety-critical component. Any inconsistency in casting density, heat treatment depth, or tooth profile accuracy can lead to accelerated chain wear, premature tooth breakage, or complete undercarriage failure. To eliminate every external variable, cqctrack operates from a self-built industrial campus where all production lines are fully company-owned. We outsource none of the core manufacturing steps.

Every sprocket assembly produced under part number 46A0124 passes through a complete in-house chain:

• Incoming alloy steel chemistry verification via optical emission spectrometry
• Precision casting of the sprocket ring from high-grade alloy steel
• CNC machining of the tooth profile, bolt circle, pilot bore, and mounting faces
• Full-ring through-hardening and tempering heat treatment
• 100% non-destructive flaw detection on every sprocket
• Dimensional metrology against LiuGong engineering tolerances
• Surface anti-corrosion treatment and final quality release

Because every process is contained within our own factory, the sprocket you receive today is dimensionally and metallurgically identical to the one you will receive next year — stable, repeatable, and fully traceable to raw material heat numbers and production batches.

3. OEM Manufacturing Partnerships and a Catalog of Over 20,000 Undercarriage Parts

Our manufacturing credibility is built on direct OEM supply. cqctrack serves as an OEM manufacturing partner for leading global brands, including:

• LiuGong
• Hitachi
• XCMG
• KOBELCO
• SDLG (LGCE)

We produce undercarriage components that are fitted directly onto new machines on these manufacturers’ assembly lines, strictly conforming to their technical drawings, material specifications, and audit requirements. Our direct OEM relationship with LiuGong means the 46A0124 sprocket is not reverse-engineered from a worn sample — it is manufactured with an inside understanding of LiuGong’s load ratings, dimensional stack-ups, and heat treatment specifications.

For the worldwide aftermarket, our active product catalog has grown to more than 20,000 individual part numbers, covering track rollers, carrier rollers, idlers, sprockets, and complete track chains. This depth ensures that whether you need a single 46A0124 final drive sprocket for a CLG950 or a complete undercarriage package for a mixed fleet, we can supply the correct, engineered parts without guesswork.

4. Inside the 46A0124 Final Drive Sprocket: Alloy Steel Casting, Full-Ring Heat Treatment, and 100% NDT

Here is exactly how cqctrack builds the final drive sprocket wheel assembly for the LIUGONG CLG950 to deliver the structural integrity and wear life that severe-duty operation demands.

Alloy Steel Casting — The sprocket ring is produced from a high-grade alloy steel casting, formulated for deep hardenability, high tensile strength, and excellent fatigue resistance. The alloy chemistry ensures that each tooth can withstand continuous impact and sliding wear from the track bushings, while the ring body resists cracking under the enormous torque loads transmitted by the final drive hub. For the CLG950’s lightweight chassis, the casting is designed to provide maximum strength with optimized material distribution, reducing unnecessary mass without compromising durability.

Full-Ring Heat Treatment and Tempering — After casting and preliminary machining, the sprocket undergoes a complete full-ring through-hardening and tempering heat treatment. This is not a localized surface hardening that leaves soft spots between teeth. The entire ring circumference receives a uniform thermal cycle, producing consistent tooth hardness around all 360 degrees. Subsequent tempering precisely adjusts the microstructure to achieve the ideal balance between maximum surface wear resistance and core toughness.

100% Non-Destructive Testing (NDT) — Every single finished sprocket assembly is subjected to 100% non-destructive flaw detection before it enters final dimensional inspection. Using magnetic particle and ultrasonic testing, we scan for any sub-surface cracks, porosity, shrinkage cavities, or inclusions that could initiate fatigue failure under load. A sprocket with an undetected internal flaw may look perfect on delivery but fail catastrophically after a few hundred hours. Our NDT regime eliminates that risk.

Strict Dimensional Tolerance Control — All mounting and interface dimensions — the bolt hole circle, pilot bore diameter, flange face runout, and tooth profile geometry — are machined and verified within the tolerances of the original LiuGong engineering drawings. This ensures that the 46A0124 sprocket bolts directly onto the final drive hub without modification, maintaining perfect chain meshing and preventing the uneven wear that arises from even slight misalignment.

5. One Source for the Complete Undercarriage System and More

A final drive sprocket is just one element of the crawler undercarriage. At cqctrack, we manufacture the entire undercarriage wearing package under one roof, using one unified quality system:

• Track rollers (bottom rollers):51C0306
• Carrier rollers (top rollers):51C0308
• Front idlers (guide wheels):51C0307
• Drive sprockets (final drive wheel assemblies):46A0124
• Complete track chain assemblies with shoes:
• Bucket teeth and adapters (for excavator applications):

Because all these components share the same metallurgical standards, heat treatment profiles, and dimensional disciplines, they wear as a compatible system. For a LIUGONG CLG950, sourcing your 46A0124 sprocket together with our rollers, idlers, and track chains ensures a harmonized undercarriage system with predictable wear rates — extending the interval between major rebuilds and lowering your total cost per operating hour.
